1, brightness: the difference in brightness of the LED, the prices are different. LED for LED lamps shall comply with laser level class I standards.
2, antistatic antistatic ability LED, long life and high prices. Antistatic LED to greater than 700V typically used for LED lighting
3 wavelength LED, wavelength, same color, same color if required, higher prices. No LED light color meter manufacturers is difficult to produce color products.
LED 4, leakage current is a one-way electric light, if there is a reverse current, it is called leakage, leakage current of LED, short life, low prices.
5, light angle uses different LED beam angle is different. Special angle, the higher the price. Such as the scattering angle, the higher the price.
6 different quality is the key to life, life, life determined by the light failure. Lumen maintenance, long life, long life, high price.
7, chip LED light chip, different chips, prices vary widely. Japan and the United States more expensive chips, Taiwan and domestic chip prices lower than that of Japan and the United States.
8, chip wafer size is expressed in length, chip LED the quality is better than a small chip. Price is proportional to the chip.
9, gel colloidal General ordinary LED to epoxy resin, reinforced with a UV-resistant and fireproofing agent LED to higher prices, Outdoor LED lighting should be of high quality UV-resistant and fire. Each product has a different design, different design suitable for different purposes.
